He's donated his slithering serpent to to a celebrity auction which will benefit Pencils of Promise, an organization which funds schools in some of the poorest parts of the world.

Though it'd be a dream for some fans to grab Justin Bieber's Johnson (LOLz!), the website writes a warning to potential bidders:

"Keeping a pet snake is a long term responsibility. Before making any decision about keeping one, please ensure you have the money, space, knowledge, time, resources and enthusiasm required to properly care for the species you intend to keep, for the duration of its life."

The winner must also guarantee that they can provide veterinary care.

Sounds like a great way to raise money for a good cause and snag some Bieber swag.
